Fig. 1 shows one half of a window-screen and casing. The other half is of similar construction throughout.

It isobvious that the construction of the parts above described may be varied without departing from the principles which I have applied, and I do not wish to confine myself to the exact construction specified.

In the alternate constructionthe tongue 16 is'formed with offsets 24, which form resilient connections with the flanges 8 and 9 to retard thesliding movement of the frame.

Having described my invention, what I claim as new, and desire to protect by Lettel-"s Patent, is

1. A window-screen having a frame made from thin metal, the sides and corners of which have overlying sections, said sections comprising longitudinal intermeshing ribs and grooves and flanges on their inner and outer edges and said corner-sections lapping over the ends of said side sections, screennetting between said inner flanges and ribs, and means for fastening said sections together.

2. A window-screen, consisting of a frame madefrom thin metal, the sides-and corners of which have overlying sections comprising Ion itudinal intermeshing ribs and grooves am? flanges on their inner and outer edges, said corner-sections engaging said side sections, material'between all of said sections to be heldin said frame, and means for clamping said sections to engage said material.

3. A device of the class set forth, consisting of a frame made from thin metal, the sides and corners of which have overlying sections, said sections comprising longitudinal intermeshing ribs and grooves and flanges on their inner and outer edges, said corner-sections engaging said side sections, material between said sections to be held in said frame, and means for clamping said sections to engage said material, said flanges on said outer edges being separated to form a groove, for thepur- .poses specified.

4. A device of the class set forth, consist- '50 in of a frame made from thin metal, the

'Si es and corners of which are formed by overlying sectlons, said sectlons comprising longitudinal ribs and grooves and flanges on their inner and outer edges, said corner-sections lappin over said side sections, material between sai sections and passing between the flanges on said inner edges, means for clamping said sections together to hold said material, said flanges on the outer edges of said sections being separated to form a guidinggroove all in combination with a windowcasing aving a tongue in said guidin groove on which said frame is adapted to sli e.

5. A rectangular window-screen having its sides formed by front and back sections, the ends of which overlap, said sections comprising longitudinal intermeshing ribs and grooves and flanges on their inner and outer edges, screen-netting between said front and back sections, cornerepieces having corresponding ribs lap ing over the ends of said side sections, an means for clamping said sections together.

6. A window-screen having a rectangular frame, the sides and corners of which have two overlying sections, said corner-sections lapping over the ends of said side sections, and all of said sides and corners comprising lon itudinal intermeshing ribs and rooves and anges on their inner and outer e ges, screen-nettlng between said sections, and means for clamping said sections together.

7. A device of the class set forth, consisting of a frame formed by a pair of overlying sections, having longitudinal intermeshing ribs, flanges on the inner and outer edges of said sections, said outer flanges being separated to form a move, material passing between said inner anges in said ribs to be held in said frame, means for clamping'said sections to hold said material, a window-casing, and a tongue on said window-easing in said groove, formin a resilient connection with the flanges at t esides of said groove.

8. A window-screen having a rectan lar frame, the sides and corners of which ave two overlying sections, said's'ections having tongues formed upon their ends which lap over each other, said sections comprising lonitudinal intermeshing ribs and grooves and l iaving flanges on their inner and outer edges, screen-netting between said sections, means for clamping all of said sections and fastening said tongues to hold said screen-netting and the parts of said frame, a window-casing, and tongues on said'window-casing, said outer flanges and the tongues on said'window casing forming a spring engagement for holding said frame and permitting 1t tos'iidein said casing. 9. A window-screen having a frame, the sides-and corners of which have two overlying sections, said cornersec'tions lap ing over the ends of said side sections and a l of said side and corner sections comprisinglongitudinal intermeshing ribs and grooves and flanges on the innerand outer ed es, screennetting between said sections, resi ient strips between said ribs and netting, and means for clamping said sections together.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
